Definitions

  • the present invention relates to the field of treatment of effluents from processes producing liquid effluents loaded with organic materials and has for its object a process and an installation for the treatment of effluents of the type mentioned, particularly wine-making effluents essentially in the form of wash water.
  • the quantity of pollution is thus directly proportional to the quantity of wine produced.
  • the daily quantity is quite variable and the washing which follows withdrawal can thus quadruple the mean daily production.
  • the problem posed by the present invention accordingly consists in overcoming the mentioned drawbacks and in designing a process and an installation for the treatment of effluents loaded with organic material, more particularly wine-making effluents, constituting a simple, suitable and efficacious solution, which is reliable and less costly as to time and permitting responding to the most strict regulatory requirements as to the discharged effluents.
  • the present invention has for its object a process for the treatment of effluents loaded with organic materials, particularly wine-making effluents essentially in the form of wash water, characterized in that it consists principally, for each treatment cycle, in pouring the effluents to be treated, as produced, into a storage basin and actuating a recirculation circuit between this latter and a reactor adapted particularly to oxygenate said effluents, in actuating a superoxygenation device integrated with the storage basin, when the volume of stored effluents is too great to avoid passing into anaerobic phase, this whilst maintaining the circulation through the reactor, then stopping the superoxygenation and maintaining the circulation at a minimum level avoiding the passage into anoxia of the effluents, when the latter achieves certain minimum pollution conditions, simultaneously and progressively pouring the effluents on at least one unit of purification solids and discharging the purified effluents, until leaving substantially only the residual sludge of decan
  • the invention also has for its object an installation for the treatment of effluents loaded particularly with organic materials, particularly for practicing the process described above, characterized in that it is principally constituted by at least one storage basin suitable to the volume of effluents to be treated during a treatment cycle, at least one reactor connected to the storage basin or basins by a recirculation circuit, at least one superoxygenation device disposed in the or each storage basin, and one or several units of purification solids supplied with pretreated effluents from the reactor.
  • FIG. 1 is a schematic top plan view of an installation according to the invention.
  • FIG. 2 is a detail cross-sectional view of a units of purification solids forming a part of the installation shown in FIG. 1.
  • the treatment process according to the invention consists principally, for each treatment cycle, in pouring the effluents to be treated, as produced, into a storage basin 1 and actuating a recirculation circuit 2 between this latter and a reactor 3 adapted particularly to oxygenate said effluents, in activating a superoxygenation device 4 integrated into the storage basin 1, when the volume of stored effluents is too great to avoid passing into an aerobic phase, this whilst maintaining the circulation through the reactor 3, then stopping the superoxygenation and maintaining the circulation at a minimum level avoiding the passage into anoxia of the effluents, when these latter meet certain minimum pollution conditions, in simultaneously and progressively pouring the effluents onto at least one purification solids unit 5 and removing the purified effluents, until leaving substantially only residual decantation sludge more or less mineralized in the storage basin 1, and, finally, treating as desired at least a portion of the latter sludge to suppress the organic components present and to lead to a substantially inert
  • the residual sludge is present after extraction of the liquid effluents comprised, on the one hand, decantable materials in suspension that are hardly biodegradable, and, on the other hand, biological sludges produced during the anaerobic purification process.
  • the density of these sludges is not uniform: from 150 grams per liter for those which rest on the bottom, they proceed to 20 grams per liter in the so-called "sludge cloud" at the liquid/sludge interface.
  • the most biodegradable are the lightest, and are hence located at the surface.
  • the treatment of the residual sludges consists preferably in operating the superoxygenation device 4 and the recirculation circuit 2 substantially to the maximum of their capacity and to entrain the light component of the residual sludges, comprising the highest content of organic material, toward the superoxygenation region for its degradable and its mineralization in aerobic phase, so as to give a minimum quantity of residue constituted of mineralized sludges, which are heavy and inert.
  • the extraction of the sludges can be carried out, for their spreading, for example, at the end of summer which lends itself to their absorption by the soil.
  • the final inert sludges can also, as a function of the quantities produced and the capacity of the storage basin 1, remain stored in said basin for complete extraction and cleaning every five years, for example.
  • the effluents be subjected to screening or degrilling, if desired associated with decantation, before being pouring into the storage basin 1.
  • the pouring of the effluents from the reactor 3 onto the purification solids 5 is carried out in a sequential manner, by transferring a portion of the contents of the reactor 3 toward said solids 5 at each cycle, when the pollution level of said portion is below a predetermined threshold value.
  • the oxygenation reactor 3 for injecting products promoting purification into the storage basin 1 via the recirculation circuit 2 and for measuring and monitoring at least one parameter indicative of the pollution level, for example chemical and/or biological oxygen demand measured in the effluents, to determine the proper time to inject at least a portion of the contents of the reactor 3 onto the solids 5, when minimum pollution conditions are satisfied (such as a COD less than 1 g/l).
  • a parameter indicative of the pollution level for example chemical and/or biological oxygen demand measured in the effluents
  • injectable products promoting purification can be particularly cited the silicone based products of the type known as RHODORSYL of the CRAY-VALLEY company, as well as different biologically active commercial preparations containing for example bacteria and/or yeast selected for their purification properties.
  • the reactor 3 thus permits carrying out for example measurements, if desired combined, of respirometry and/or of suspended materials, whilst serving to contain the decantation of the effluents before their pouring onto the purification solids 5.
  • the sequential operation of the reactor 3 permits controlling very precisely the development of the pollution level of the effluents and avoiding transferring these latter, or a portion of these latter, except when minimum pollution conditions are reached.
  • the purification solids 5 will be supplied sequentially with predetermined quantities of effluents suitable for the surface of said solids and whose pollution level permits optimum treatment by this latter, thereby guaranteeing minimum pollution at the level of the effluents finally discharged.
  • the recirculation of the effluents during the superoxygenation phase also permits homogenizing the effluents stored, by the generation of currents promoting mixing of these latter.
  • the purification solids 5 consist of one or several units of quantities of sand whose characteristics and dimensions are determined such that the limiting factor of the bacterial development in the solids will be lack of carbon and not lack of oxygen.
  • the purification solids 5 can be subjected to vacuum, by application of suction within the body of sand so as to promote aeration of the surface layer 5' of the solids 5 receiving in the first instance the effluents from the reactor 3, carrying out an oxygenation of said solids 5 and a discharge of the gases produced.
  • each treatment cycle lasts substantially 365 days, this cycle time being subdivided time-wise into several consecutive periods corresponding to the different treatment operations, namely, for example, a first period of about 10 days, beginning with the grape harvest and corresponding to aerated storage of the effluents poured with recirculation and oxygenation, a second period of 40 to 110 days, preferably about 90 days, corresponding to the superoxygenation phase, a third period of 100 to 250 days, preferably about 200 days, corresponding to a minimum recirculation, to a decantation of the materials in suspension from the effluents stored in the basin 1 and to a progressive and sequential pouring of said liquid effluents onto the purification solids 5 from the reactor 3 after verification of the minimum pollution conditions and, finally, a fourth period of about 65 days corresponding to the mineralization of the residual sludges and, as the case may be, their removal from the
  • This water is easily fermented and the autumn temperature promotes the development of microorganisms of the anabacterial type.
  • This type of anaerobic bacteria produces bad smelling gases, particularly methyl mercaptan, hydrogen sulfide and methane.
  • the path of recirculation between the reactor 3 and the storage basin 1 permits maintaining a level of oxidation permitting the appearance of bad odors.
  • the settled effluents contained in the storage basin 1 can decant under optimum conditions. Simultaneously, the dwell time of the effluents is extended in the reactor 3, permitting on the one hand new development of the purifying biomass, and on the other hand a maintenance of the effluent saturated in dissolved oxygen.
  • the present invention also has for its object an installation for the treatment of effluents loaded particularly with organic materials, and adapted particularly, but not in a limiting manner, to the practice of the treatment process described above.
  • This installation is principally constituted, as shown in FIG. 1 of the accompanying drawings, by at least one storage basin 1 adapted for the volume of effluents to be treated during a treatment cycle, at least one reactor 3 connected to the storage basin or basins 1 by a recirculation circuit 2, at least one superoxygenation device 4 disposed in the or each storage basin 1, and one or several units 5 of purification solids supplied with pretreated effluents from the reactor 3.
  • the storage and decantation basin 1 preferably has a shape facilitating the removal of residual sludges and rendering it adapted to receive a superoxygenation device 4 which permits, by supplying a suitable oxygen level, quickly bringing the biological pollution to an acceptable level for the final treatment in the purification solids 5 of the type of a body of sand.
  • the installation can comprise a screening or grilling station 6, as the case may be provided with a scraper, disposed upstream of the storage basin 1 and stopping for example the particles having a cross section greater than 1 cm 2 .
  • the reactor 3 can be disposed within the storage basin 1, and can comprise a system for oxygenation by diffusion of fine bubbles and be provided with injection means for chemical and/or biological products promoting purification and means for analysis of the effluents, particularly as to their degree of pollution and/or oxygenation.
  • This biological reactor 3 preferably of vertical structure, is provided with a recirculation pump integrated into the recirculation circuit and with an injection pump for the effluents onto the purification body 5, adapted to be actuated sequentially for sequences of injection of effluents of several minutes per hour.
  • Said reactor 3 could for example consist of a reactor of the type of those produced by the company CALONA-PURFLO.
  • the suction and reinjection of the effluents into the storage basin 1 by the recirculation circuit 2 are carried out respectively at two opposite ends of said basin 1 so as to create a flow or a current of effluents passing through this latter, substantially parallel to the current generated by the initial pouring of the effluents into said basin 1 and directed particularly toward the superoxygenation device 4.
  • the superoxygenator could itself consist for example of a superoxygenator of the type known as C3201 from the FLYGT company.
  • each unit of purification solids 5 comprises a layer of silica sand having a granulometry comprised between 2 mm and 6 mm, a coefficient of uniformity of 3.5 and a size determined such that the limiting factor of the bacterial development in the solids will be carbon deficiency.
  • the purification mass 5 will be dimensioned such that the sequential pouring of the effluents from the reactor 3 produces, in said body, a lower water layer at about 10 cm/m 2 /day, preferably lower than 5 cm/m 2 /day.
  • This body preferably has a thickness comprised between 30 and 80 cm, preferably about 60 cm.
  • the different units of purification body 5 form an assembly comprising a system for division of the effluents under pressure (expansion valve 8), which permits sprinkling and hence using all of the surface of the body, the purification body itself constituting the support of the biomass and formed of a layer of silica sand, and a system of recovery of purified effluents located at the base of the body and comprised by recovery drains 9 with a large slot permitting the partial recovery itself of the effluents to direct them toward the superficial hydraulic medium and permitting, as the case may be, the taking of specimens of analysis.
  • each unit of sand body 5 is subjected to underpressure by suction at the base of the unit 5 in question, this underpressure permitting replacing permanently the carbon dioxide of the biological respiration with a fresh supply of oxygen to promote a limitation of the bacterial development by carbon deficiency.
  • the suction can be provided by connection to the compressor, supercharger or aerator 3' of the oxygenation system of the reactor 3, for example by means of a siphon device 10.
  • the installation according to the invention could also comprise at least one control and direction unit 7 of the process, for example of the programmable automatic type, which automatically controls the progression of the successive treatment cycles, being associated with detectors 7' and suitable actuators.
